MYSQL JSON_SET 添加反斜杠

Question

我想更新數據庫中的 JSON 數組

我有這個數組：

Array
(
    [id] => 34
    [var1] => val1
    [var2] => val2
    [var3] => val3
)

我需要通過 id 更新 json

查詢示例：

JOSN_SET(`json_arr`,'$."34"','{"id":"34","var1":"val1","var2":"val2","var3":"val3"}')

預期結果：

{"34":{"id":"34","var1":"val1","var2":"val2","var3":"val3"}}

結果：

{"34":"{\"id\":\"34\",\"var1\":\"val1\",\"var2\":\"val2\",\"var3\":\"val3\"}"}

謝謝您的幫助。

Answer 1

您應該將其轉換為 JSON，例如：

JOSN_SET(`json_arr`,'$."34"',CAST('{"id":"34","var1":"val1","var2":"val2","var3":"val3"}' AS JSON))
